Wow... Randall you have some incredible images. Plus you get such a variety. Beautiful stuff.
I have done a lot of slide show videos lately and thought I would share a simple trick that I think creates a smoother video. Also... as feedback....
Your images are so beautiful that we need a little more time to soak in the beauty..... In this case, I think less is more.... As an example I just put together a short sample slide show so you can see what I am talking about. I chose 7 images. Each image is 3 seconds in duration with a 1 second fade transition between each. The fade transition seems to take all the jerky motion out of the video. So, this nets out to a 15 second video.
Thought I'd share,
Greg
